Abstract
A device for the injection of a fuel/gas mixture is particularly simple and cost-effective for gas containment of fuel emerging from an injection valve. For this purpose, a treatment attachment is provided at the downstream end of the injection valve, the treatment attachment including at least a gas containment part and an insert body which are fixedly connected to one another. The treatment attachment is fixedly connected to the injection valve by means of a casing portion of the bowl-shaped gas containment part, while a bottom portion of the gas containment part has material of the insert body at least partially injection-molded around it. Inside the insert body extends an orifice which at least partially widens conically in the downstream direction and in which, for example, a jet divider is arranged. The device is particularly suitable for injection into the suction pipe of a mixture-compressing spark-ignition internal combustion engine.
